Let's open up my web browser with all my standard tabs.

讓我們打開我的網絡瀏覽器，打開所有的標準選項卡。

I've got to open up my report in my slide deck.

我得打開幻燈片中的報告。

Oh, I might need to reference this spreadsheet and better put on some music, too.

哦，我可能需要參考一下這個電子表格，最好還能放點音樂。

But before I get started, let's just play a quick game of Solitaire.

不過在開始之前，我們先來玩一局接龍游戲。

We've probably all been in a situation like this.

我們可能都遇到過這樣的情況。

The number of applications you're trying to run exceeds the computing power of your device, and it starts to slow down or crash.

您嘗試運行的應用程序數量超過了設備的計算能力，設備開始變慢或崩潰。

Your brain works the same way.

你的大腦也是這樣工作的。

We have a finite amount of mental resources or bandwidth to devote to any given task, and once that amount is met or exceeded, we tend to get overwhelmed or give up.

我們用於任何特定任務的精神資源或帶寬都是有限的，一旦達到或超過這個數量，我們就會不堪重負或放棄。

This concept is called cognitive load, and it's a critical one for designers to be aware of.

這一概念被稱為認知負荷，是設計師必須意識到的一個重要概念。

The cognitive load imposed by a user interface is the amount of mental resources that is required to understand and operate the system.

用戶界面帶來的認知負荷是指理解和作業系統所需的心理資源量。

Because the human brain can't be upgraded like a slow computer, it's our job as designers to accommodate the limitations of our users' brains.

因為人腦不能像慢速電腦那樣升級，所以作為設計師，我們的工作就是要適應用戶大腦的侷限性。

There are two types of cognitive load to be aware of, intrinsic and extraneous.

需要注意的認知負荷有兩種，即內在負荷和外在負荷。

Intrinsic cognitive load can't be eliminated.

內在認知負荷無法消除。

This is the effort that is required to keep track of goals and absorb new information.

這就是跟蹤目標和吸收新資訊所需的努力。

Let's imagine that I'm checking my banking app to look at my account balances.

假設我正在查看我的銀行應用程序，查看我的賬戶餘額。

Intrinsic load is the brainpower needed to comprehend and take in those numbers once I see them.

內在負荷是指我看到這些數字後，理解和接受它們所需的腦力。

Extraneous cognitive load, on the other hand, is all of the stuff that gets in the way of my goal and takes up my valuable limited brainpower.

另一方面，外在認知負荷則是所有妨礙我實現目標、佔用我寶貴而有限的腦力的東西。

Things like remembering my password, figuring out which account is which, or even understanding the text on the screen.

比如記住我的密碼，弄清哪個賬戶是哪個賬戶，甚至理解螢幕上的文字。

This is what designers should be working to minimize or eliminate.

這正是設計師應該努力減少或消除的。

Three quick tips for doing just that.

做到這一點的三個快速提示。

First, avoid visual clutter.

首先，避免視覺雜亂。

If it distracts the eye, it's going to distract the brain.

如果它分散了眼睛的注意力，就會分散大腦的注意力。

Remove things like irrelevant images or lavish typography that can slow down a user trying to complete their task.

刪除不相關的圖片或華麗的排版，因為它們會拖慢用戶完成任務的速度。

Second, build on existing mental models.

第二，以現有的思維模式為基礎。

Most of us have spent a lot of time browsing websites and software and have gotten used to a fair number of conventions.

我們中的大多數人都花了大量時間瀏覽網站和軟件，習慣了相當多的約定俗成。

Don't break those conventions if you don't have to.

如果沒有必要，不要打破這些慣例。

If the conventional way works, that's probably how you should do it too.

如果傳統方法行之有效，那麼你也應該這樣做。

And third, offload tasks.

第三，卸載任務。

Consider if there are any steps in the process that could potentially be handled by the interface itself, thus taking a little bit of the load off of the user.

考慮流程中是否有任何步驟可以由界面本身處理，從而減輕用戶的負擔。

Relying on biometrics instead of password entry or redisplaying previously entered information are great examples of offloading human tasks to machines.

依靠生物識別技術代替密碼輸入或重新顯示以前輸入的資訊，都是將人類任務卸載給機器的很好例子。

So keep those designs simple and maybe even have a little more empathy for your poor sluggish computer.

是以，請保持設計簡潔，或許還能對你那可憐的遲鈍電腦多一點同情。
